I’ve been following Alison’s posts on YouTube for a few months now. She recently purchased a Gen 3 night vision scope with a 5x lens and attachment for her HD video camera. On the very first night out with her new scope, Alison picks up an object which releases a thin beam of light towards the ground. Alison points out in the video, that there is an abandoned coal mine right in the vicinity of this laser “scan”. This is certainly worth a look and if you are interested in following Alison’s channel in YouTube, it’s right here.
